標籤：連結   python3   知識庫   調用   http   dev   測試   mkdir   org   

1. 安裝依賴環境

# yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

 

 

wget https://www.python.org/ftp/python/3.5.2/Python-3.5.2.tgz

 

3. 建立Python3的目錄

# mkdir /usr/local/python3 

 

4. 解壓下載檔案並切換目錄

# tar -zxvf Python-3.5.2.tgz

# cd Python-3.5.2.tgz

 

5. 執行

# ./configure --prefix=/usr/local/python3

# make && make install

 

6. 建立Python3的軟連結

# ln -s /usr/local/python3/bin/python3 /usr/bin/python3

 

7. 建立Pip3的軟連結

# ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

 

8. 測試命令 python3 和 pip3

# python3

# pip3

 

安裝保留了原python命令調用python2
